Us Weekly broke the news last month that Cyrus, 22, and Schwarzenegger, 21, were dating. Soon after, the two were seen making out at a USC Trojans game. Their romance has been in the works for some time, according to Schwarzenegger, who named Cyrus as his longtime crush in a 2011 interview with Details. Arnold Schwarzenegger's son unabashedly told the mag then that his "eye" was and has always been "set on Miley Cyrus."

Interestingly enough, this isn't Rory Kennedy's first time remarking about a high-profile pop star dating someone within the Kennedy clan.

In 2012, the documentary filmmaker told Us that she "couldn't be more thrilled" that her nephew Conor Kennedy was dating Taylor Swift. "I think she's fantastic," Rory said then. "She's a good friend of our family and we all adore her and love her. It's great to have her around."
